Window Replacement in the Yorkshire Dales National Park

The short answer

Inside the National Park, the National Park Authority is the planning authority. Replacing windows on an unlisted house may still be permitted development, but listing, conservation areas, Article 4 directions and planning conditions (common on barns) can change that. Check your address is inside the boundary first.

Key takeaways

Check the boundary — it moved in 2016
The NPA publishes design guidance
Barns often have window conditions

Towns like Skipton are outside; villages like Grassington are inside. The Authority's guidance favours designs that respect Dales building traditions, while allowing well-justified contemporary work.

When it works well

Designs that respect the building's character

When it may not

Assuming the same rules as the district outside the park

Common mistakes

Not checking the boundary
